  • Tube Diameter: 1 inch

  • Compact and lightweight design

Cons:

Eye Relief & Eye Box:
Eye relief sits around 3.2 inches—comfortable for a Crosman 2100 setup. The eye box is generous enough for quick target acquisition.

Durability:
Built with the “True Strength” platform, it easily withstood over 500 pellets during my testing without zero drift.

Elevation & Windage Knobs:
The tactile, lockable turrets provide audible ¼ MOA clicks. I performed a box test and found consistent tracking accuracy.

Magnification & Parallax:
The AO (Adjustable Objective) works beautifully for airgun ranges—from 10 to 50 yards—with precision focus.

Comes with two quick-detach rings compatible with 11mm and Weaver rails—perfect fit for the Crosman’s rail once adapter mounts are installed.

Personal Experience:
Mounted on my Crosman 2100 using UTG dovetail-to-Weaver adapters, zeroing took only 15 shots. After over 400 rounds, zero held tight, and the illumination proved helpful in shaded woods.

A nearly perfect optic for the Crosman 2100—offering adjustability, durability, and clarity in a compact form.
